Open linear stapler

An open linear stapler, comprising an end effector located at a distal side, wherein:

• the end effector comprises a substantially U-shaped stationary jaw located at the distal side and a movable jaw movable relative to the stationary jaw to clamp tissue therebetween, a surface of the stationary jaw opposing the movable jaw comprising an anvil, and the movable jaw being configured to receive a staple cartridge,
• wherein the stationary jaw comprises an inner anvil clamping plate, two substantially U-shaped outer anvil clamping plates, and a distal surface of the anvil is fixedly connected to proximal surfaces of the distal ends of the outer anvil clamping plates,
• wherein a gap is provided between the inner anvil clamping plate and the anvil.

An open linear stapler, comprising an end effector located at a distal side, wherein:

• (a) the end effector comprises a substantially U-shaped stationary jaw located at the distal side and a movable jaw movable relative to the stationary jaw to clamp tissue therebetween, a surface of the stationary jaw opposing the movable jaw comprising an anvil and the movable jaw being configured to receive a staple cartridge, the anvil including a coating and an outer surface, the coating being over the outer surface,
• (b) the stationary jaw comprises two substantially U-shaped outer anvil clamping plates, and a distal surface of the anvil is fixedly connected to proximal surfaces of the distal ends of the outer anvil clamping plates.
